    means, adjacent the front end, for attaching said planter to planter conveying means;

    means for supporting said frame at a desired height above a surface of soil;

    a shaft mounted to the frame, oriented at an acute angle to and transversely of the longitudinal axis;

    soil groove cutting means, consisting of a plurality of circumferentially spaced individual groove forming tines extending away from the shaft and all lying substantially in a single plane normal to the shaft, supported by said shaft for free rotation about the axis of the shaft and positioned to interact with the soil, said acute angle being such that the tines of the soil groove cutting means will be rotated about said shaft axis by their interaction with the soil during forward motion of the planter in the direction of travel, all said groove forming tines being angled to extend, adjacent their ends, circumferentially in a direction opposite to the direction of said rotation of the soil groove cutting means to produce, during said forward motion of said planter in the direction of travel, a sequential plurality of discrete parallel open topped grooves in the surface of that soil, each said groove extending transversely of the direction of travel at an acute angle thereto; and

    means attached to the frame for supplying seed to said open topped plurality of grooves subsequent to their formation.
